The "timer" tool is a chronometer starting at the rising side of the equation giving the start signal.
The current value of the timer is incremented by 1 at each tenth of a second.
To use this type of tool, one carries out comparisons on the value of elapsed time which is incremented beginning at the start of the timer.
This method is very elegant because the complete management, of traffic lights for instance, can be easily resolved using only one counter.
Moreover, it is a good approach for programming an electronic cam.
The RAZ signal reinitializes and set the timer value to 0.
